z
The device cannot communicate with the RADIUS server (you can determine by pinging the
RADIUS server from the device) — Take measures to make the device communicate with the
RADIUS server normally.
Symptom 2 : RADIUS packets cannot be sent to the RADIUS server.
Possible reasons and solutions :
z
The communication links (physical/link layer) between the device and the RADIUS server is
disconnected/blocked — Take measures to make the links connected/unblocked.
z
None or incorrect RADIUS server IP address is set on the device — Be sure to set a correct
RADIUS server IP address.
z
One or all AAA UDP port settings are incorrect — Be sure to set the same UDP port numbers as
those on the RADIUS server.
Symptom 3 : The user passes the authentication and gets authorized, but the accounting information
cannot be transmitted to the RADIUS server.
Possible reasons and solutions :
z
The accounting port number is not properly set — Be sure to set a correct port number for RADIUS
accounting.
z
The device requests that both the authentication/authorization server and the accounting server
use the same device (with the same IP address), but in fact they are not resident on the same
device — Be sure to configure the RADIUS servers on the device according to the actual situation.
